摘要

Methyl 5-(N, N-dimethylamino)-2, 4-pentadienoate (tert-aminodienylester 1) was synthesized by condensation of methyl crotonate (2) with N, N, N', N'- tetramethylmethylenediamine (3). The reactivity of 1 was investigated with methyl propiolate (4), dimethyl 2-butynedionate (5), dimethyl maleae (6), dimethyl fumarate (7), 2-buten-4- olide (8), 2-cyclohexenone (9), styrene (10), trans-β-nitrostyrene (11), 1, 4-benzoquinone ( ...
